The necklace worn by Princess Leia is titled "Planetaariset Laaksot" which means "Planetary Valleys" and was made by Lapponia of Helsinki. It was the creation of jewelry designer Björn Weckström. When Lucasfilm purchased the necklace the designer wasn't told what the film was about and was surprised to see his necklace worn by Carrie Fisher in a movie, which "later became a cult". *
